UNITED STATES PATENT OFFICE` ROBERT MORRIS, OF SALEM, INDIANA.

IMPROVEMENT IN REAPlNG-MACHINES.

Specification forming part of Letters Patent No. 57.549, dated August28,1666.

To all whom it may concern:

Be it known that I, ROBERT MORRIS, of Salem, in the county of Washingtonand State oflndiana, have inventeda new and ImprovedGrain-DischargingDevice for Harvesters; and l do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing' had to the accompanyin g drawings, forming part of thisspeciiication, in Which- Figure l is a side view of a portion of myinvention 5 Fig. 2, a side sectional view ot' the same, taken in theline x m, Fig. 2; Fig. 3, a plan or top view ot the same.

Similar letters of reference indicate like parts.

Thisinvention relates to a new and improved device for discharging grainin gavels from harvesters 5 and it consists or" endless carriersinconnection with a rotary gavel-discharger provided with a regulatingattachment for determining the size of the gavels or rendering thein ofuniform size.

A represents a series of horizontal endless belts7 which work aroundrollers a a inserted in the platform B, on which the cut grain isdischarged. These belts are provided with projections b to catch the cutgrain and cause it to be carried along by the movement ofthe belts.

O represents a series of inclined belts which work over an inclinedplane, D, and have projections c attached to them like those on thebelts A. By means of these endless belts the` support the inclined sidepieces, d d. On one end of the shaft of this gaveldischarger there issecured or formed a square, h, on which a bar, G, bears, said barserving as a check to prevent the discharger from turning more than aquarter ot' a revolution at each movement. (See more particularly Fig.l.)

The bar Gr is pressed upon the square by means of a spring, H, andgraduating-screw t, said spring being attached at one end to bar G, andthe screw passing through an arm, j, secured to one of the side pieces,d.

The grain, as it falls over the upper end ot' i the inclined plane D,drops into a compartment or chamber, f, of the discharger, which is heldin position under the pressure of the bar G until a sufficient quantityof grain has fallen into the chamber to overcome that pressure, and thedischarger then rotates a quarter ot' a revolution, the filled chamberdischarging itselt and an empty one passing in position to receive thegrain from the upper en'd of D, the iap preventing the grain fromfalling over or beyond the discharger. By turning the setscrew i thepressure ot' the bar G on the square It may be graduated in order thatthe cut grain may be discharged in gavels of greater or less size, asmay be desired, and the spring H may have an index, 7c, attached, towork over a graduated arc, to indicate the pressure of bar G on thesquare h, and consequently the weight and size of the gavel. v v

Having thus described my invention, I claim as new and desire to secureby Letters Patent-m l. The square h and spring H, operating with thedischarger F, substantially as and for the purpose specified.

2. The index lo and set-screw t', in combination with the spring H,arranged with the bar G and square h, substantially as described, forthe purpose specified.

ROBERT MORRIS.
